SAFETY ATTACHMENT FOR GAS COCKS.

Original application filed May 27, 1927,

This invention relates to improvements in safety attachments for gascocks or the like as for instance described in my copending application,Serial No. 194,693, filed May 27, 1927, of which this is a division. Itis the principal object of my invention to provide a device topositively prevent an acci dental opening of a closed cock so as toavoid loss of life ZtIlC damage to property or in jury to persons by thegas escaping from a jet left inadvertently open or accidentally opened.after the flame has been extinguished.

It is well known that the cocks of gas burners particularly gas rangesafter being in use for any length of time become loose and worn, andthus liable to, he accidentally turned on when the gas is not to beused, and it is the principal object of my invention to provide anattachment positively preventing such an accidental opening of the gascocks and to ell ectively lock the cock, in its closed position, whileallowing a ready removal of the attachment when not to be used.

Another object and purpose of my invention is the provision of a simpleand therefore inexpensive device of this kind, yet durable and efficientin operation.

A further object of my invention is the provision of a gas cockattachment for resiliently locking the cock in its closed positionadapted to be readily attached to and removed from a gas burner.

These and other objects and advantages of my invention will become morefully known as the description thereof proceeds, and will then bespecifically defined in the appended claims.

In the accompanying drawing forming a material part of this disclosureFigure lshows in side elevation, partly in section, a gas stove cockequipped with my novel safety device of a slightly modified form.

Figure 2-is a section on line 2-2 of Figure 1.

As illustrated on the drawing, my device is particularly intended foruse as a gas range attachment to prevent an accidental opening of a gascook on a kitchen stove or Serial No. 194,693. Divided and thisapplication filed October 5, 1927. Serial No. 224,107.

the like, and comprises a cap 18 of springy or elastic material adaptedto be snapped over the handle 19 of the cock, while the body part 20 ofthe device is bent out of the plane of the cap 18 and has a dependingfork 21 formed therewith adapted to engage or straddle the valve casingfor the cock, designated 22 for the valve controlling the supply of gasthrough pipe 23.

The operation attachment will be entirely clear from the abovedescription. If a cock is to be locked in its closed position, the capis snapped over the handle 19 in its closing position illustrated inFigure 2, and the prongs of the fork 21 are placed in position tostraddle the valve casing. It will ev dently be not possible to open thevalve without first to remove the cap and body.

It will be understood that while I have shown and described as examplesthe preferred form of my device, the same may be subjected to manymodifications coming within the scope of the appended claims Withoutdeparting from the spirit of my invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A locking device for the operatinghandies of gas valves comprising a body, a horizontal cap formed withsaid body and adapted to be sprung over the operating handle, and adepending member on said body having substantially fork-shape adapted tostraddle the valve body.

2-. A locking device for the operating valves of kitchen rangescomprising a body of springy material, a horizontal, slitted cap formedwith said body and adapted to be sprung over the operating handle of thevalve, and a substantially vertical depend ing member bent laterally outof the plane of said cap and having fork shape, the prongs of said forkadapted to straddle the valve body for preventing accidental opening ofthe valve.
